Weight capacity for a Murphy or wall bed varies according to the size, style and manufacturer. An example is the Supreme Model manufactured by International Murphy Beds, which supports 1,700 pounds. The load capacity for the same company's Elite Model is up to 2,000 pounds.

Any room should be tall enough for side-mount beds. For a vertical twin or full, you need at least 82 1/2 inches; for a vertical queen, you need at least 87 1/2 inches.

A Murphy bed (in North America), also called a wall bed, pull down bed, or fold-down bed, is a bed that is hinged at one end to store vertically against the wall, or inside a closet or cabinet.
